"When you think "excavator," images of digging dirt and rock on land may come to mind. However, that’s not the case for J.F. Brennan Company, Inc., a 100-year-old marine construction contractor out of La Crosse, Wisconsin. Brennan is serviced by Nortrax, New York."

In 2019, good fortune shone on Brennan's Environmental group as we procured a winter river restoration project in Rhode Island. The general scope for this project remained along the lines of past work, where we restore river depths to facilitate and improve water quality, fish migration, but this one came with a twist; its footprint was tightly nestled within the low bridges and bustling infrastructure of Waterplace Park in downtown Providence, RI.
Two-thirds of the way through in October 2019, we visited the Lake Zumbro Restoration Project in Oronoco, Minnesota. This video examines the project goals, the team involved and takes a close look at the 80-acre confined disposal facility. Thank you to the lake community, our clients, and all stakeholders on this project.
J.F. Brennan Company turns 100 in 2019. We are proud to join the ranks of centurion companies who survived and succeeded during times of monumental change. We grew from our humble beginnings on the northeast Iowa frontier to become a change leader, using innovation and technology to work more safely and efficiently. From what began as a partnership between brothers, has turned into a nationally recognized marine solutions company celebrating its 100th year in business.

2018 marked our 10th year dredging on the Fox River. Here is a quick video on our progress so far.
In January 2018 we dredged 6,000 Cubic Yards out of the Winnapaug Pond in Westerly, Rhode Island. Despite cold temperatures, the project finished up in less than 6 days.
No roads, No Problem! Our amphibious excavators and dumptrucks are the perfect tools for wetland work!
J.F. Brennan Company was highlighted for the OEM equipment that we use in our marine construction and environmental remediation work.
In 2016 our divers hydraulically dredged over 1,000 cubic yards of contaminated sediments from the Waukegan Harbor North Ditch. All material was hydraulically pumped into geotextile tubes where the sediment was dewatered and loaded out for disposal.
In 2016 Brennan worked to restore the Ninigret Salt Marsh Wildlife Refuge in Rhode Island from damaged caused by Hurricane Sandy in 2012.
In 2015 we teamed up with our GLSR partners to remove sediment and invasive phragmites from a 5-mile long stretch of wetlands in Harsens Island, Michigan.
Brennan has revolutionized sediment capping possibilities with its newly patented Broadcast Capping System (BCS™). This system uses the principles of hydraulic transport to deliver clean sand and granulated activated carbon to a distribution barge where it is rapidly dewatered and unobtrusively spread over the bottom of the waterway. Brennan’s sediment capping system can accurately place materials up to 3 inches in diameter, while achieving a homogenous thickness with even distribution.
This is a brief description of hydraulic dredging and geotextile tube dewatering.
